This is an oldie, but we rarely see this kind of optical illusions in its full effect. Ok, this is what I want you to do: count how many different colors you can see in this spiral below. Unfortunately color-blind individuals will only see a grayish pattern, so this won’t work for them (those of you can remain occupied reading this article). Rest of you, be sure first to notice that there are two different shades of pink, and then you may start counting. Most of us will end up with 4 different colors (2 pinkish ones, blue and a green). Well this was the wrong answer! Yes, you heard me right. There are actually only 3 colors present here. To see what I mean, check the second picture. It shows you how this image would look like if we removed those pinkish colors in background. Amazing, isn’t it? You may recall candy stripes we posted waaay back. It’s almost the same!
